SEATTLE

Kubota Vision Inc. (“Kubota Vision”), a clinical-stage specialty ophthalmology company and wholly-owned subsidiary of Kubota Pharmaceutical Holdings Co., Ltd. (Tokyo 4596), announced today the submission of novel Vascular Adhesion Protein-1 (VAP-1) inhibitor compounds discovered by Kubota Vision to the U.S. National Cancer Institute (NCI) Developmental Therapeutics Program (DTP) for screening in the NCI-60 Human Tumor Cell Lines Screen. The NCI DTP will evaluate the compounds’ anti-tumor activity against 60 human cancer cell lines from nine types of tumors, including leukemia, lung, colon, breast, prostate, brain, kidney, ovarian and skin cancer.

During R&D activities to develop innovative therapeutics for inflammatory eye conditions, Kubota Vision discovered several novel VAP-1 inhibitors that are very potent and highly selective. VAP-1 inhibitors, also known as Semicarbazide-Sensitive Amine Oxidase (SSAO) inhibitors, are a promising new class of drugs being developed primarily to treat inflammation-driven diseases. While Kubota Vision has focused on eye inflammation, VAP-1 inhibitors can also be potentially used for the treatment of certain types of cancer. Cancers reported to be associated with VAP-1 include colorectal cancer, lung cancer, gastric cancer, liver cancer, kidney cancer, melanoma, and certain brain tumors. In particular, VAP-1 plays a role in harmful cell trafficking, which occurs during tumor progression and the metastatic spread of cancer. Therefore, VAP-1 inhibitors may be effective in treating or preventing metastatic cancer.

The NCI-60 Human Tumor Cell Lines Screen has served the global cancer research community for over 20 years. The NCI-60 screen uses 60 different human tumor cell lines to identify and characterize novel compounds with growth inhibition or killing of tumor cells. Up to 3,000 small molecules, synthetic or purified natural products, can be screened per year for potential anticancer activity. This screen also allows for prioritization of selected agents for further evaluation by the NCI in collaboration with the submitting company.

Ryo Kubota, MD, PhD, Chairman, President and CEO of Kubota Vision Inc., stated, “We are grateful and honored that the NCI DTP, a historical and proven program with over 20 years of achievement, will provide us with the opportunity to screen our VAP-1 inhibitors in the NCI-60. It is exciting that our VAP-1 inhibitor projects found during a target discovery phase have the potential to be used as cancer treatments.”
